Therefore, it is necessary to provide a steel column strength testing device for steel production to solve the aforementioned technical problems. Utility Model Content
[0004] The technical problem this invention aims to solve is that existing steel column strength testing devices require adjustment based on the size of the steel column during actual use, but lack a convenient clamping structure, resulting in reduced adaptability. To address these shortcomings, this invention provides a steel column strength testing device for steel production, including a support base. A rectangular through-hole is formed on one side of the support base. A bidirectional screw rod, penetrating the support base, is rotatably connected to the inner side of the rectangular through-hole. Symmetrically screwed to the outer side of the bidirectional screw rod are movable plates slidably connected to the rectangular through-hole. By rotating a handwheel, this invention drives the connected bidirectional screw rod to rotate, controlling the two outer movable plates to move the limiting plates in opposite or opposing directions. This provides the ability to limit the movement of steel columns of different sizes. Furthermore, anti-wear rollers are provided on the limiting plates to prevent obstruction of steel column deformation. This invention solves the technical problem of existing steel column strength testing devices requiring adjustment based on the size of the steel column during actual use, but lacking a convenient clamping structure, leading to reduced adaptability.

Each movable plate has a limit plate fixedly installed on both sides, and multiple anti-wear rollers are rotatably connected to the opposite surfaces of the two corresponding limit plates.
[0006] Furthermore, a base is fixedly installed at the bottom of the support, and a pressure display is embedded in the front surface of the base.
[0007] Furthermore, a support plate is fixedly installed on the upper surface of the base, and hydraulic telescopic rods are symmetrically embedded on the top of the support plate. Each hydraulic telescopic rod has a pressure block fixedly connected to its output end.
[0008] Furthermore, a pressure sensor is fixedly installed on the inner side of the pressure block, and the pressure sensor is electrically connected to the pressure display.
[0009] In a further configuration, the other end of the bidirectional screw passes through the support base and is fitted with a circular block. Multiple insertion slots are evenly provided on the outer side of the circular block. A U-shaped block is fixedly installed on the rear surface of the support base. A tension spring is fixedly installed on one side of the U-shaped block. One end of the tension spring is fixedly connected to an insertion piece that passes through the U-shaped block. One end of the insertion piece is inserted into the insertion slot.

[0011] Compared with related technologies, the steel column strength testing device for steel production provided by this utility model has the following beneficial effects:
[0012] This utility model provides a steel column strength testing device for steel production. By rotating the handwheel, the connected bidirectional screw rotates, controlling the two movable plates on the outer side to move the limiting plate in opposite or opposite directions.

[0019] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings show typical embodiments of this utility model.
[0020] Example 1:
[0021] like Figure 1-4 As shown, the present invention discloses a steel column strength testing device for steel production, comprising a support base 6, a rectangular through hole 12 on one side of the support base 6, a bidirectional screw 11 rotatably connected to the inner side of the rectangular through hole 12 and passing through the support base 6, and movable plates 10 symmetrically screwed to the outer side of the bidirectional screw 11 and slidably connected to the rectangular through hole 12. Limiting plates 4 are fixedly installed on both sides of each movable plate 10, and multiple anti-wear rollers 9 are rotatably connected to the opposite surfaces of the two corresponding limiting plates 4.
[0022] like Figure 1 As shown, a base 7 is fixedly installed at the bottom of the support 6, and a pressure display 8 is embedded in the front surface of the base 7. This display shows the pressure value when the downward-pressed steel column deforms.
[0023] like Figure 3 As shown, a support plate 1 is fixedly installed on the upper surface of the base 7. Hydraulic telescopic rods 3 are symmetrically embedded on the top of the support plate 1. A lower pressure block 2 is fixedly connected to the output end of each hydraulic telescopic rod 3. A pressure sensor 13 is fixedly installed on the inner side of the lower pressure block 2. The pressure sensor 13 is electrically connected to the pressure display 8.
[0024] In practice, by rotating the handwheel 5, the bidirectional screw 11 connected to it is rotated, thereby controlling the two movable plates 10 on the outside to move the limiting plate 4 in opposite or opposite directions, thus enabling the limiting of steel columns of different sizes. In addition, the limiting plate is equipped with anti-wear rollers 9, which prevents the deformation of the steel column from being hindered. This solves the technical problem that existing steel column strength testing devices need to be adjusted according to the size of the steel column during actual use, but lack a convenient clamping structure, resulting in reduced adaptability.
[0025] Example 2:
[0026] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: the other end of the bidirectional screw 11 passes through the support base 6 and is sleeved with a circular block 18. Multiple insertion slots 17 are evenly opened on the outer side of the circular block 18. A U-shaped block 14 is fixedly installed on the rear surface of the support base 6. A tension spring 15 is fixedly installed on one side of the U-shaped block 14. One end of the tension spring 15 is fixedly connected to an insertion piece 16 that passes through the U-shaped block 14. One end of the insertion piece 16 is inserted into the insertion slot 17. The insertion piece 16 has an L-shaped structure and is located inside the tension spring 15.
[0027] In practice, a circular block 18 is provided on the outside of the bidirectional screw 11, and multiple insertion slots 17 are evenly provided on the outside of the circular block 18. At the same time, the elastic tension of the tension spring 15 is used to make one end of the insertion fastener 16 connected to it inserted into the insertion slot 17, thereby enhancing the firmness of the limiting plate 4 after adjusting the position and enhancing the stability of the steel column limiting.
[0028] In use, the steel column is first placed on the upper surface of the inner cavity of the support base 6. Then, the insert 16 is pulled to stretch the tension spring 15, causing one end of the insert 16 to disengage from the insertion groove 17 opened in the circular block 18. At the same time, the handwheel 5 is turned to drive the bidirectional screw 11 connected to it to rotate, which drives the two outer movable plates 10 to move the limiting plate 4 in opposite directions, so that the anti-wear roller 9 contacts the steel column, thereby limiting the steel column of different sizes. Then, the insert 16 is released. At this time, under the elastic tension of the tension spring 15, one end of the insert 16 connected to it is inserted into the insertion groove 17. Finally, the hydraulic telescopic rod 3 is activated, causing the lower pressure block 2 connected to its output end to move downward and apply pressure to the steel column. When the steel column deforms, the pressure display 8 displays the pressure value at this time.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
